System and method for searching information

Abstract

Provided are a system and method of searching information. The system comprises: a database comprising a data storage area in which data is divided into a plurality of data blocks and stored, and metadata storage areas; a searcher configured to receive, from a user, a keyword search request comprising a targeted keyword and a targeted search range, and to search the data stored in the database using the targeted keyword in a keyword search; and a keyword manager configured to receive, from the searcher, keyword absence information generated from a result of the keyword search, and to store the keyword absence information in the database.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to and the benefit of Republic of Korea Patent Application No. 10-2013-0058950 filed on May 24, 2013, the disclosure of which is incorporated herein by reference in its entirety.BACKGROUND[0002]1. Field[0003]The present disclosure relates to technology for efficiently searching a large amount of data, and more particularly, to a system and method for searching information.[0004]2. Discussion of Related Art[0005]The proliferation of Internet services, such as an electronic commerce, social network service (SNS), and voice over Internet protocol (VoIP), has lead to the development of various means for effectively operating systems for these services. In general, a service system stores and manages log data, such as access records and error records of users, event data of events having occurred in the system, or so on. Such data can be helpfully used in grasping the state of a service system, a service compone...

AI Technical Summary

Benefits of technology

[0008]The present disclosure is directed to providing a means for effectively searching a large amount of data, such as log data.

Problems solved by technology

As a service system is complicated and increases in size and the number of users of the service system increases, the amount of data recorded in the service system also increases.

However, it is very difficult to estimate in advance which piece of data will be frequently searched for by a user, and additional hardware resources are consumed for indexing.

Thus, such a method is particularly inefficient in the case of a large amount of data.

Such an unstructured database does not support automatic indexing of specific data, and thus it is required to implement an indexing algorithm for indexing.
